Q:Breifly explain the brake system in the lifting devices ex. Over head crane?
Cranes work using hydraulics and cables. The cables are wrapped around pulleys and the pulley is turned using hydraulic power. The brake system is simply stopping the pulley from turning by reducing power. The hydraulic system typically will turn a series of gears which in turn spins the pulley that the cable is wrapped around. It's different than a brake system say on a car where when you hit the brakes, pads squeeze on the interior of the wheel rim slowing it down. Cranes you just reduce power and stop the pulley from turning. They also have emergency stops. Older cranes have wedges that would be released onto the cable and then the wedges would grab the cable and slip into a ring. The narrow end of the wedges would slip into the ring first and then as the wedges increased in diameter the grip on the cable would get tighter and then stop the cable from moving. They also have systems on the pulleys to stop the pulley from spinning. They essentially work the same way as a car break. When the emergency brake is triggered, pads will squeeze on the rim of the pulley to stop it. These mechanisms work by friction. They could also have holes around the pulley and a steel pin would be pushed into one of the holes to stop it from spinning. Of course if the force of the weight exceeded the strength of the pin, it would shear.
Q:What is tower crane? What are the types and features?
According to the movement can be divided into: walking type and fixed type. The fixed tower crane tower body can not be fixed, installed on the whole concrete foundation, or installed on the strip or X concrete foundation, and the walking type can be divided into four types: caterpillar type, automobile type, tyre type and track type. In the construction of housing, the general use of fixed type. It can be divided into two kinds of horizontal boom, luffing and luffing of luffing arm according to its variable amplitude. According to its installation form, it can be divided into three kinds: self lifting, integral quick dismounting and assembling. The most widely used are down slewing, rapid dismounting, track type tower cranes and self elevating tower cranes which can be used with four machines (track type, fixed type, attached type and internal climbing type).

Q:I am looking for a print/lithograph of William J Wilgus' Ichabod Crane and the Headless Horseman.
Preach is son! I know in my case I ask if something looks good on me or if I look good because half the time I can't tell if something looks hideous on me or not. I always used to get picked on when I was younger as well because i grew up in an area where everybody was blonde haired and blue eyed, and I'm italian with extremely dark features so I stuck out! The popular girls tore me apart and I coudln't STAND to look at myself in the mirror. Yuck, dark, dark times. But then again, those girls were just trying to make themselves more secure, and they're the kinds of people fishing for compliments. heh.

Q:How to do a simple Fujian White Crane block?
To get it spot on as you say, it would be best to get it from your instructor. Videos are sometimes good and sometimes bad. In any case they are a bad way to learn something. They simply can't correct things. And that is assuming that the video shows them correctly in the first place. Learn from a competent instructor.
